Just Starting My Multi Family Journey

[Eric Nuernberger]

I just started my own personal 90-day challenge on June 1st.  My goal is to find a multi-family to buy and hold in my area.  I am currently looking at a few different properties and trying to make sure I have most of my costs accounted for.  I am trying to estimate my insurance and maintenance costs.  Right now I am estimating 15% of the rent per door.  I also have the taxes (based on last year) broken down to a per month cost + 2%, and my loan monthly payment accounted for as well as 85% of units rented out throughout the year.  My question would be am I missing any big costs or are my estimates not high enough.  I will be self-managing and appreciate other's posts that have given me thoughts on how to increase value within properties as I have been looking that others are not capitalizing on currently.  

Any and all thoughts would be appreciated.
